Answer 1

Ответ:

Пошаговое объяснение:

(х+18)*(13/10-х)=0

х+18=0

13/10-х=0

х1=-18

х2=1,3

Answer 2

To solve the equation (x + 18) * (1.3 - x) = 0, we can set each factor equal to zero and solve for x. This is because the product of two numbers is equal to zero if and only if at least one of the numbers is equal to zero. Therefore, we have two possibilities:

1. Setting x + 18 = 0: Subtracting 18 from both sides, we get: x + 18 - 18 = 0 - 18 x = -18

2. Setting 1.3 - x = 0: Subtracting 1.3 from both sides, we get: 1.3 - x - 1.3 = 0 - 1.3 -x = -1.3 Dividing both sides by -1, the equation becomes: x = 1.3

Therefore, the solutions to the equation (x + 18) * (1.3 - x) = 0 are x = -18 and x = 1.3.
